Evidence from census and newspaper records proves the Wilkins family traveled to Utah in 1851. His obituary that appears in the Journal History, also states that he came to Utah in 1851.
The family appears in the Iowa census in 1850 (taken in October). First documentation to place them in Utah is the rebaptism of John Gansworth Wilkins in the Utah Stake City Ward on 1 January 1852.
Further research is needed to determine the name of the pioneer company they traveled to Utah with.
